Chicoma Mountain, the highest point in New Mexico’s Jemez Mountains, rises on the northeast rim of the Valles Caldera and stands prominently across northern New Mexico. Its Tewa name, Tsikumu Pʼin, means “obsidian-covered mountain,” and it is also spelled Tschicoma or Tchicoma. Because the tree line is unusually high in this part of the range, the mountain remains forested almost to its summit, giving it a distinctive shape. Sacred to many Puebloan peoples as the “center of all,” much of it lies within Santa Clara Pueblo territory. The nearby Puye Cliff Dwellings further place it within the region’s intertwined geologic and cultural history.
